The present invention relates to improvements in brushing or sweepingdevices and has reference more particularly to an attachment for a motorvehicle equipped with pneumatic tires, the primary object of theinvention residing in the provision of a brushing attachment forclearing the path of the front wheel of the vehicle of and removingtherefrom, broken glass, nails, tacks or any other obstructions that maybe encountered and which would puncture or otherwise damage thepneumatic tires of the front wheels of a vehicle.

One of the important objects of the invention resides in the provisionsof a brush attachment that can be readily and easily installed on anautomobile without necessitating any material alterations of the partswith which the brushing attachment is associated,

the device being at all times positiveand efficient in carrying out thepurposes for which it is desired.

A further object is to provide a brush attachment for vehicles of theabove mentioned character wherein means is provided for adjusting theheight of the brushing or sweeping member with respect to the ground,additional means being provided to permit swinging movement of the brushhead when the same strikes a large obstruction so that the brush headmay pass over said obstruction without causing damage to the brushattachment.

Still a further object is to provide a brush attachment wherein theparts are so arranged as to deflect the broken glass, nails or the liketo one side of the road.

Still a further object is to provide a brush head attachment of theabove mentioned character which is simple in construction, inexpensive,strong and durable and further well adapted to the purposes for which itis designed.

Other objects and advantages will become apparent during thecourse ofthe following description.

In the accompanying drawing, forming a part of this specification,and inwhich like numerals indicate like parts-throughout the same:

Serial No. 321,500.

Figure 1 represents a front elevation of the brush attachment embodyingour invention showing the manner in which the same is mounted on anautomobile.

Figure 2 is a side elevation showing front and rear brush units,

Figure 3' is a vertical sectional view through one of the brush units,

Figure 4 is a top plan view for more clearly disclosing the attachingmeans for a brush unit,

Figure 5 is a sectional View taken approximately on the line 55 ofFigure 4 looking in the direction of the arrows,

Figure 6 is a sectional view taken on the line 6-6 of Figure 3,

Figure 7 is a detail view showing the means for adjustably securing thelower frame in the stationary upper frame and,

Figure 8 is a detail perspective View of the removable brush.

In the drawings wherein for the purpose of illustration is shown thepreferred embodiment of our invention, the numeral 1 designates asubstantially rectangular. shaped channeled frame that is curved assuggested in Figure 6.

This frame is disposed in front of as well as directly rearwardly ofeach of the front wheels A of an automobile. The supporting means forthe frame disposed forwardly of each front wheel includes the upper andlower rods 2 and 3 respectively. The forward ends of these rods aresecured to the inner side portion of the frame 1 while the rear end ofsaid rod has connection with a vertical plate 4 that is disposed againstthe front axle B in the manner as clearly suggested in Figures 4: and 5.

A similar plate 5 is disposed against the rear side of the'front axleand suitable securing bolts 6 extend through the unner and lower ends ofthe alined plates 4 and 5 for engagement with the upper and bottom'facesof the front axle to rigidly secure the plates in position as also shownin Figure 5.

Additional rods 7 extend from the stationintermediate portions of therods 2 and 3 and brace rods 9 extend laterally from the cross piece 8 toa plate 10 that is disposed against the front side of the front axle Binwardly of the plate 4.

A plate 11 is secured against the rear side of the/front axle B inalinement with the plate 10 by bolts 12.

The stationary frame of the rear brush unit is supported in a similarmanner. The rods that extend from the plate5 to the frame of the rearbrush units are shown at 13 and 14: respectively while the brace rodsthat extend from the plate 11 are indicated at 15.

Upon referring to Figure 7 it will be observed that the frame 1 isprovided in its front side with a screen 16, the edges of the screenbeing disposed within suitable channels formed in the respective sidesof the frame. j Each brush unit includes a slidable lower frame 17 whichis also slightly curved and this frame 17 is slidable between thechanneled sides of the stationary upper frame 1 through the bottom ofthestatio'nary frame. A handle 18 extends across the rear portion oftheslidin'g frame 17 for manually raising and lowering the "frame andfor the purpose of holding the slidable frame in any vertically adjustedposition with respect to the stationary upper frame 1, we provide theset screws 19 that extend through the opposite sides ofjthe stationaryframe l'and'en gage with the adjacent side edges of the slidable framein the manner as also clearly disclosed in Figure 7.

The slidingframe 17 is covered with -a screen 20. Each brush unitfurther includes edge of this strip of rubber being attached to thelower edge of the sliding frame 17 by "suitable clamping plates orstrips 24; as shown in :Figure 3. V

The purpose of the rubber connecting strlp .23 between the frame 17 andthe brush head from the rear side of the housing 27, the

lower edgeof thisfplate terminating above the ground engaging portionsof the bristles 28. A

When the brush units are positioned in front of and directly behind thefront wheels of the automobile, the lower frame 17 is properly adjustedso that the bristles 28 engage the ground, it will be readily apparentthat the bristles of the brush and the brushes will sweep away to oneside any obstacles such as pieces of broken glass, nails, tacks "andother sharp elements from the path of readily and easily atmchedinproper position on the automobile without -Iit-lcess'itating anyalterations. I

Furthermore the brush attachment will at all times bepositive andefficient in carrying out the purpose for which it is designed and dueto its simplicity the same can be manufactured at a very lowcost and yetbe strong and durable. v

Should the bristles 28 wear away so as to -render the brush ineflicientin its operation,

the brush may be readily andeasily removed and replaced vv'ith a newone. i Y Y While we have shown thepreferred embodiment of our invention,it is tojbe understood that various changes in the size, shape "andarrangement ofpartsmay be resorted to without departing from "the spiritof the invention'a'nd the scope ofthe appendedclaims.

7 Having thus described our invention, What we claim as new is:

,1. In a brush attachment for automobiles,

a'vertical member for disposition infront'of each of the front wheelsgofthe automdbile,

supporting means for said member, an additional member having its upperportion slid- -ably associated with the stationary firstmentionedmember, means for adjustably securing'the movable member with respect tothe stationary member, a brush for engagement with the ground, and aflexible connection between the brush and thelower [edge of theslidablemember, said flexibleconnection'comprising a strip of stiffrubber secured at its lower endto the head of the brush, the upper edgeof the 'strip of rubber "being secured "to the loweredge of the slidablemember.

,2. In brush attachment for automdbiles, "a vertically disposedchanneledframe for "arran-gement in front of each of the front wheels of anaut'omobile, supporting means therefor, a screen mounted 'inthestationary frame, an additional frame'slidably mounted in the channeledframe, a screen carried by't'he slidable frame, means for adj ustablysecuring the slidable frame in any vertically adjusted position, a brushfor engagement with the ground, and resilient means interconnecting thebrush and the lower edge of the slidable frame.

3. In a brush attachment for automobiles a vertically disposed channeledframe for arrangement in front of each of the front wheels of anautomobile, supporting means therefor, a screen mounted in thestationary frame, an additional frame slidably mounted in the channeledframe, a screen carried by the slidable frame, means for adjustablysecuring the slidable frame in any vertically adjusted position, a brushfor engagement with the ground, and a strip of stiff rubber secured atits lower edge to the head of the brush, the upper edge of the strip ofrubber being secured to the lower edge of the slidable frame.

In testimony whereof we affix our signatures.
